Clear victory for the record chaser
New Actros is fuel efficiency world champion
It is now official: the new Actros is the most fuel-efficient truck of all times. At the Record Run 2011 between Rotterdam and Szczecin, it not only achieved the targeted fuel saving in comparison with its predecessor. Rather, it was already clear after Dr. Jörg Zürn, Head of Development at Mercedes-Benz Trucks, had waved the finish flag: the new Actros was even more frugal than expected on the 10,000 kilometres of the seven-day shuttle drive. The exact figures measured by DEKRA: the new Actros 1845 Euro V achieved a reduction of 7.6 per cent. The new Actros 1845 Euro VI recorded a corresponding figure of 4.5 per cent.
The targets set for the Record Run 2011, which came to an end in Rotterdam early on Sunday, were six to seven and three to four per cent respectively. The comparative vehicle was the Actros 1844 LS BlueTec 5 in the Nardo configuration, but with a standard semitrailer. This was the truck that won an entry in the “Guinness World Records” in 2008 in Nardo, Italy, as the world’s most fuel-efficient series production truck.
Tested under everyday conditions
The consumption figures of the two new Actros trucks are even more impressive in view of the rules of the Record Run 2011. Unlike the drive in Nardo, the comparative run was not carried out on a test circuit but under everyday conditions: on sometimes extremely busy motorways and, at times, under adverse weather conditions. Both had a negative impact on consumption. The drivers at the wheel of the trucks with standard semitrailers and gross combination weights of 40 tonnes respectively were not Mercedes-Benz driver-trainers, but professional drivers. As on normal long distance work, they travelled at an average speed of 80 km/h. In other words, they drove under everyday conditions.
Tremendous effort for the measurement
The effort that was put into guaranteeing proper measurement was anything but everyday in character: one day before the official start on 26 June, DEKRA expert Jens Lohmann already thoroughly checked the vehicles. With seals and adhesive tapes, he prevented all possibilities of any prohibited fuelling or weight reduction. During the comparative drive he monitored every fuelling of diesel and AdBlue as well as the swapping of the semitrailers. The aim of the latter was to rule out that differences in the rolling behaviour of the semitrailers might distort the measurement data. Lohmann captured all steps taken on photo camera. He finally submitted the official result to the persons concerned in the form of a printed documentation.
After traveling for more than 10,000 km, the Record Run 2011 of three Mercedes-Benz trucks reached its destination at midnight.
It is 4:57 p.m. in Peine, and the Actros Record Run 2011 will soon go into its final round.
